Songs of Sacred Harp

The story of American music is, in many ways, the story of discovery and rediscovery of blues and gospel and country rolling into rock and pop and Aaron Copeland.

But one American musical tradition is so old and so other-worldly that it's hardly ever touched the modern mainstream. It's called Sacred Harp — and the harp is the human voice, raised in something like prayer.

It started in colonial New England, and migrated south. Now its bold, haunting sound has fans all over.
